OIL REGISTER FOR INTERNAL-COMBUSTION ENGINES.

J Application filed March 2, 1925. Serial No. 12,684,

To all whom it mag concern: 7

Be it known that I. CHESTER YOUNGS, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Im rovements in Oil Registers for Internal-( mmbus'tion Engines, of which the following is a specification.

My invention relates to improvements in means for-determining when oil should be renewed in internal combustion engines, and particularly in automobile engines, and its objects are: first, to provide a register that may be used in conjunction with the speedometer in the automobile to determine how many miles have been traveled since having renewed the oil supply in the crank case of the engine: second, to provide a means wherewlth it may be readily noted when the renewal of oil should be made in crank case. I attainthese objects by the mechanism and. arrangement of parts shown in the accompanying drawing, in which Fig. 1 is a front elevation of my register as it appears u on the front cross board of. an automobile. Fig. 2 is a bottom plan of the same. Fig. 3 is a back elevation of the same showing the relative positions of its several parts. Fig. 4 is a sectional plan of the same taken as from the line 4-4 of Fig. 3 with the register case turned end for end, and with one of the registering dials depressed to show its position when disconnected from the locking bar for adjusting the dial as desired, and, Fig. 5 is a front elevation of one of the dials showing the indexes thereon, and with the actuating knob removed.

Similar reference characters indicate similar parts throughout the several. views where said parts occur.

In the construction of thisregister I use the several discs 7 having the ten digits, 1, 2, 3, 4, 5, 6, 7, 8, 9, and O, thereon-as shown in Fig. 5. These discs are securely attached to the ends, of the actuating stems 4, which are made to pass through the casing 2 and have springs 6 for forcing the stems outward from the surface of the casing, and the surface of the discs solidly against the inner surface of said casing, where they are held from rotating by the points 9, on

a the stop plate 8 passlng into the notches in the periphery of the discs, as shown in Fig. 3, so that, normally, one of the several digits on each disc will be held in position to show plainly through one of the openings 5-in the case 2 of the register, and is there held securely by the'lockmg plate 8 as hereinbefore stated.

The case 2 is provided with a wing 3 at each end by means of which it may be secured to the dash or cross bar 1 of the automobile, in near proximity to the speedometer.

hen 0 crating this register I find the most satis .actory results are attained as follows: We will say the s edometer registers 15,000 miles of travel w en oil is placed in the crank case, and it is desired to renew it v each five hundred miles of travel. In this case I set the dials at 15,500, five hundred miles higher than the speedometer indicates,

and when the speedometer has reached the 15,500 mile mark, corresponding with my register, I again renew the oil in the crank case, and so on, each time when it is desirable to renew the oil being indicated by the registering on the speedometer correspending with the registering on this register.

It will be noted that the locking plate 8 is securely mounted upon the inner surface of the case 2 and the discs are soplaced that the points 9 on the plate 8 will engage the desired notch in the periphery of the disc. When it is desired to change the discs to exhibit a new set of numbers I press backwardly upon the desired stem, 4,-as indicated at 4, until the disc 7 is positioned entirely out of contact with the points on the plate 8, as" indicated in Fig. 4, when the disc may be revolved, by the stem 4, into the desired position relative to the digit on the disc 7 and the openings 5 in the case, when the stem 4 is relieved and the spring 6 forces it back into position to be properly engaged by the corresponding point 9 onthe plate 8, as hereinbefore explained.

It is to be understood that means other than those herein stated, may be used to operate and lock the discs without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new in the art, is:

In a register for displaying any desired combination of numerals in a direct line, an enclosing case, a series of revoluble discs mounted in said case in a direct line, stemscase having a row of openings parallel with to be made to interlock with the desired the row of openings through which the disc notehes'in the peripheries of the discs to stems pass, springs for holding the discs hold the discs temporarily in desired po- 10 in normal positions, each disc having a sitions.
